Search for jet extinction in the inclusive jet-p(T) spectrum from proton-proton collisions at root s=8 TeV

The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7 fb-1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale.

Complex modal analysis of a slender vertical rotor by finite elements method

In this paper, natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical modal and complex analysis. The equation that rules the movement was obtained through the Lagrangian formulation. The model considered the effects of bending, torsion and axial deformation of the shaft, besides the gravitational and gyroscopic effects. The finite element method was used to discretize the structure into hollow cylindrical elements with 12 degrees of freedom. Mass, stiffness and gyroscopic matrices were explained consistently. The classical modal analysis, usually applied to stationary structures, does not consider an important characteristic of rotating machinery which are the methods of forward and backward whirl. Initially, through the traditional modal analysis, axial and torsional natural frequencies were obtained in a static shaft, since they do not suffer the influence of gyroscopic effects. Later research was performed by complex modal analysis. This type of tool, based on the use of complex coordinates to describe the dynamic behavior of rotating shaft, allows the decomposition of the system in two submodes, backward and forward. Thus, it is possible to clearly visualize that the orbit and direction of the precessional motion around the line of the rotating shaft is not deformed. A finite element program was developed using MATLAB (TM) and numerical simulations were performed to validate this model. Natural frequencies and directional frequency forced response (dFRF) were obtained using the complex modal analysis for a simple vertical rotor and also for a typical drill string used in the construction of oil wells.

O ensino de física e a música: a experiência de um futuro professor frente o desafio de ensinar

Here we present an exploratory study on the subject of Physics and Music, discussing how this issue is addressed in two high schools belonging to state education network in Rio Claro – SP city. Initially, we conducted a critical analysis of the books that are used as the main tool to support the teacher in the classroom. Alert this analysis , it is possible to realize low-level content when we bring the topic into the classroom. Based in this analysis and an experimental class that was held as part of the course Teaching Practice and Supervised , the Bachelor's Degree in Physical Activity - UNESP Campus Rio Claro was an elaborate educational proposal related to Physics Teaching and Music with a thematic strategy different from the traditional approach , considering the use of experiments built with low cost (Ferreira and Ramos , 2008) materials , which can be an alternative to improve the teaching learning process student , because these experiments stimulate and provide a more dynamic and closer interaction with the objects class. We also seek to study, in greater depth , aspects of wave physics, discussing how a wave propagates in a string with its two fixed ends , which besides being a subject that is usually covered in books , is a phenomenon that is present in string instruments

Redução de empeno em barra trefiladas do aço SAE 9254

In this paper we study the process of manufacture of wire drawn steel bars 9254, from rolled wire rod. These bars are used in the automotive industry for the manufacture of coil springs, which make up the system damping of several vehicles. The wire drawing process consists of the steps of pre-straightening, shot peening, drawing, cutting and polishing. The study aims to search for the configuration of process variables, which present the best result with respect to bending. To this were maintained settings prestraightening and mechanical stripping and varied angles and stringer polish being studied to replace the spinneret with a working angle, for a string with two working angles. To assist in the analysis of the results was the tool used DOE Software Minitab, which assesses the variation in results according to each parameter and the interaction parameters. It was thus possible to determine the best condition for wire drawing
